I'd like to start a tmuxinator session when I login (Gnome on Ubuntu Lucid). I've tried variations of the following but they all execute and close the terminal window. The following have been given to 'Startup Applications'

This is not an answer, but is getting closer. See Hilltop Yodeler's post about 13u11fr09's suggested solution. The reason this question is not answered is that, AFAICT, it opens another shell session rather than the keep the initial shell session open. In the use case described that is fine - show help, then provide a shell prompt. Whereas here the requirement is to continue to use tmux via the initial shell session launched.

The issue is: in 2011 a user should easily be able to set a shell prompt to launch on startup, using Ubuntu's UI. No doubt there is lots of black magic that can be used to get the desired result. This is real a quest of the a simple solution/approach that works with Ubuntu's UI tool for launching apps on startup.

I see. And the "start thinit"? Is that supposed to be a particular session?

Anyway, I've updated it with the bundle exec, if it doesn't work, let me know how it's not working.

Apologies for the ambiguity: mux start thinit is one command, run in the Ruby gem "environment" that bundle exec sets up/provides. Will try test your suggestions to night, from memory what this did was execute the command and close the gnome terminal window - my recollection maybe faulty so will try again.

Perhaps my version of mux is different, but mine doesn't accept an argument to mux start, and mux start starts the server and returns immediately, which would close the terminal.
